[PATCH] test: fix box/net.box.test.lua result file

[Alexander Turenko <alexander.turenko@tarantool.org>]

This is the regression from a7c855e5bd486a3392138b4f743abd6cb1d13fff
(net.box: fetch '_vcollation' sysview into the module). The result file
was corrupted, because the test sometimes produces incorrect result in
the test case for on_connect / on_disconnect triggers. This issue is
tracked by #4273.

Follow up #3941.
